IMPROVEMENT IN WOODEN BUSHINGS.

Specification forming part of Letters Patent No. 222,269, dated December2, 1879 application filed October 9, 1879.

To all whom it may concern:

Be it known that 1, KING 0. GILLETTE, of the city of Brooklyn, Kingscounty, and State of New York, have invented a new and usefulImprovement in Bung-Hole, Tap-Hole, Spigot-Hole, or Vent-Hole Bushings,which improvement isfully set fort-h in the followin g specification andaccompanying drawings.

Figure 1 is a vertical cross-section of the 'wooden bushing. Fig.2 is avertical crosssection of the wooden bushing with a metal plate fastenedto its top. Figs. 3 and 4 are top views of different forms of the metalplate.

It is a well-known fact to those conversant with the trade of brewing,or other trades wherein barrels, casks, or kegs are repeatedly used,that the holes in the bungstaves and heads, wherein bungs, vents, andspigots are frequently introduced, and oftentimes with much unnecessaryviolence, become enlarged and irregular in form, and to such an extentas to necessitate the constant repairing thereof by theintroduction ofnew staves and heads, .thus adding largely to the expense andinconvenience of those using them.

Beer is generally drawn from kegs by the introduction ofa taperingfaucet, which is driven through the corked opening in the head by aheavy mallet. The inclined surfaces of thefaucet, operating as a wedge,produce a lateral pressure, which readily splits the wood where thegrain runs but one way, thereby not only losing the contents of the kegor I barrel, but rendering it necessary to introduce anew head or-stave.

This invention is intended to obviate such difficulties, or to. offera.cheap and expeditious means of overcoming them.

It is apparent that in case there should be any occasion to make suchrepairs it can be more readily accomplished by the insertion of thisbushing than by the method at present in barrel.

By an examination of the, accompanying drawings it will he observed thatFig. 1 represents a bushing made of two or more pieces or layers ofwood, secured together by glue,

screws, or other practical and well known methods, in such a manner thattheir plane surfaces may be firmly united, but having the grain of thewood in each of the rings, plates, or layers so attached running indifferent directions transversely, thereby giving additional strengthand preventing any, tendency to the splitting of the bush itself or thewood which surrounds it.

A represents the bushing, with the opening or aperture B, for theintroduction of a faucet, vent, spigot. or hung.

a, b, c, d, and 6 show the differentlayers of wood fastened together,but with the grain of the wood running transversely.

In Fig. 2, 0 represents a metal plate, secured to the outside or uppersurface of the wooden bushing A by screws. The edges of said plate fextend beyond the outer circle or periphery of the bush, to admit offastening the plate and bushing to the head or stave,

and thereby prevent its being moved from its seat when once properlyplaced. To prevent the said plate from moving laterally, a flange orextension is made at right angles with said plate, as at D, in. the formof an annular ring,- which is made to fit the outer edge of the bushingwith exactness, thus overcoming this difficulty and giving additionalstrength;

Having described my invention, what I desire to secure by Letters Patentis- 1. A wooden bushing made of two or more layers of wood, with thegrain thereof running transversely,-as and for the purposes hereindescribed and set forth.

2. The combination of the wooden bushing A, made of two or more layersof wood, with the grain thereof running transversely, and

the plate 0, as herein set forth.

3. The plate (3, having upon its inner side the annular ring, extension,or flange. D, as specified and described. y KING 0. GU LETTE. Inpresence of- JosIAH H. MACY, WALTER W. MONTAGUE. 1
